Cos got problem with the Toyota headlamp last time, its just that simple. If u like TYC u can still choose their product, not my concern anyway. The problem is not leaking, leaking all headlamp got that kind of problems, but not like the reflector chrome turn black, like fading liao. TYC is the cheapest among all. Making for Bosch is a different story cos it has to meet Bosch QC. Just like Proton car sold locally and exported, different quality.
SONAR is SAE standard and can be exported worldwide including Singapore which is very strict. I know cos I have customers from singapore.
Nope dun have website. Anyway manufacturer website a lot bullshit inside one lar, go for independent review site.
So far I haven't got problems with SONAR, DEPO and Eagle Eye.
